The Pikes, Brits Harriet and Neil, have put together a well-organized site which makes finding what you’re looking for a breeze.
If you’re in South America bike tour planning mode, you’ll want to take a look at the Ripio Road Info section (ripio roads are the unpaved ones that make for great cycling adventures).
In the Ripio Road Info section you’ll find detailed information on the state of the roads, distances, availability of food and water, traffic levels and elevation changes. This invaluable information is well-organized in an easy to follow chart. Currently, Pikes on Bikes covers Chile, Argentina and Bolivia but more countries will be added as the tour progresses north.
Next you’ll want to check out High Passes and Places. This is where you’ll find all the need-to-know information on cycling passes in South America. Here’s an example:
Abra Pacollo, La Paz, Bolivia
Name of Pass Abra Pacollo Where On the road from Sorata to Achacachi, La Paz, Bolivia. GPS Co-ords 15.89255 S, 68.65259 W. Height 4,240m Amount climbed (on ripio) 1,600m (550m) in a long morning from Sorata. How difficult we found this climb Average
A climb up from Sorata to the altiplano near Lake Titicaca. The majority of the climb is on tarmac and the gradient is gentle with virtually no steep sections (which will come as a welcome relief if you’ve just come from climbing the insane gradients on the Guanay to Consata road). Good views of Illampu and other mountains in the Cordillera Real.
Finally, if you’re just looking for a good read and some inspiring bicycle touring photos, you won’t go wrong with Pikes on Bikes. They’ve even got bicycle touring videos if you’re interested in an inside look at life on the road.
Pikes on Bikes is one of the best bicycle touring blogs for detailed information on biking South America. Have a look and start dreaming of the Andes.
